Some existing communication libraries provide pack/unpack functions for sending noncontiguous data. In these, the user explicitly packs data into a contiguous buffer before sending it, and unpacks it from a contiguous buffer after receiving it. Derived datatypes, which are described in Section Derived Datatypes , allow one, in most cases, to avoid explicit packing and unpacking. The user specifies the layout of the data to be sent or received, and the communication library directly accesses a noncontiguous buffer. The pack/unpack routines are provided for compatibility with previous libraries. Also, they provide some functionality that is not otherwise available in MPI. For instance, a message can be received in several parts, where the receive operation done on a later part may depend on the content of a former part. Another use is that outgoing messages may be explicitly buffered in user supplied space, thus overriding the system buffering policy. Finally, the availability of pack and unpack operations facilitates the development of additional communication libraries layered on top of MPI.
| MPI_PACK(inbuf, incount, datatype, outbuf, outsize, position, comm) | |

INTEGER INCOUNT, DATATYPE, OUTSIZE, POSITION, COMM, IERROR
void MPI::Datatype::Pack(const void* inbuf, int incount, void *outbuf, int outsize, int& position, const MPI::Comm &comm) const
Packs the message in the send buffer specified by inbuf, incount,
datatype into the buffer
space specified by outbuf and
outsize. The
input buffer can
be any communication buffer allowed in MPI_SEND. The output buffer
is a contiguous storage area containing outsize bytes, starting at
the address outbuf (length is counted in bytes, not elements,
as if it were a communication buffer for a message of type MPI_PACKED).
The input value of position is the first location in the output buffer to be used for packing. position is incremented by the size of the packed message, and the output value of position is the first location in the output buffer following the locations occupied by the packed message. The comm argument is the communicator that will be subsequently used for sending the packed message.
| MPI_UNPACK(inbuf, insize, position, outbuf, outcount, datatype, comm) | |
| IN inbuf | input buffer start (choice) |
| IN insize | size of input buffer, in bytes (non-negative integer) |

| IN datatype | datatype of each output data item (handle) |

INTEGER INSIZE, POSITION, OUTCOUNT, DATATYPE, COMM, IERROR
void MPI::Datatype::Unpack(const void* inbuf, int insize, void *outbuf, int outcount, int& position, const MPI::Comm& comm) const
Unpacks a message into the receive buffer specified by outbuf,
outcount,
datatype from the buffer
space specified by inbuf and insize. The output buffer can
be any communication buffer allowed in MPI_RECV. The input
buffer is a contiguous storage area containing insize bytes,
starting at address inbuf.
The input value of position is the first location in
the input buffer occupied by the packed message.
position is incremented
by the size of the packed message, so that the output value of
position is the first location in the input buffer
after the locations occupied by the message that was unpacked.
comm is the communicator used to receive the packed message.
Advice to users.
Note the difference between MPI_RECV and MPI_UNPACK: in
MPI_RECV, the count argument specifies the maximum
number of
items that can be received. The actual number of items received is determined
by the length of the incoming message. In MPI_UNPACK, the
count argument specifies the actual number
of items that are unpacked;
the ``size'' of the corresponding message is the increment in
position.
The reason for this change is that the ``incoming message size'' is not
predetermined since the user decides how much to unpack; nor is it easy to
determine
the ``message size'' from the number of items to be unpacked. In fact, in a
heterogeneous system, this number may not be determined a priori.
( End of advice to users.)
To understand the behavior of pack and unpack, it is convenient to think of the
data part of a message as being the sequence obtained by concatenating the
successive values sent in that message. The pack operation stores this
sequence in the buffer space, as if sending the message to that buffer. The
unpack operation retrieves this sequence from buffer space, as if receiving a
message from that buffer. (It is helpful to think of internal Fortran files or
sscanf in C, for a similar function.)
Several messages can be successively packed into one packing unit. This is effected by several successive related calls to MPI_PACK, where the first call provides position = 0, and each successive call inputs the value of position that was output by the previous call, and the same values for outbuf, outcount and comm. This packing unit now contains the equivalent information that would have been stored in a message by one send call with a send buffer that is the ``concatenation'' of the individual send buffers.
A packing unit can be sent using type MPI_PACKED. Any point to point or collective communication function can be used to move the sequence of bytes that forms the packing unit from one process to another. This packing unit can now be received using any receive operation, with any datatype: the type matching rules are relaxed for messages sent with type MPI_PACKED.
A message sent with any type (including MPI_PACKED) can be received using the type MPI_PACKED. Such a message can then be unpacked by calls to MPI_UNPACK.
A packing unit (or a message created by a regular, ``typed'' send) can be unpacked into several successive messages. This is effected by several successive related calls to MPI_UNPACK, where the first call provides position = 0, and each successive call inputs the value of position that was output by the previous call, and the same values for inbuf, insize and comm.
The concatenation of two packing units is not necessarily a packing unit; nor is a substring of a packing unit necessarily a packing unit. Thus, one cannot concatenate two packing units and then unpack the result as one packing unit; nor can one unpack a substring of a packing unit as a separate packing unit. Each packing unit, that was created by a related sequence of pack calls, or by a regular send, must be unpacked as a unit, by a sequence of related unpack calls.
Rationale.
The restriction on ``atomic'' packing and unpacking of packing units allows
the implementation to add at the head of packing units additional
information, such as
a description of the sender architecture (to be used for type conversion, in a
heterogeneous environment)
( End of rationale.)
The following call allows the user to find out how much space is
needed to pack a message and, thus, manage space allocation for
buffers.
| MPI_PACK_SIZE(incount, datatype, comm, size) | |
| IN incount | count argument to packing call (non-negative integer) |
| IN datatype | datatype argument to packing call (handle) |
| IN comm | communicator argument to packing call (handle) |
| OUT size | upper bound on size of packed message, in bytes (non-negative integer) |
int MPI_Pack_size(int incount, MPI_Datatype datatype, MPI_Comm comm, int *size)
MPI_PACK_SIZE(INCOUNT, DATATYPE, COMM, SIZE, IERROR)
INTEGER INCOUNT, DATATYPE, COMM, SIZE, IERROR
int MPI::Datatype::Pack_size(int incount, const MPI::Comm& comm) const
A call to MPI_PACK_SIZE(incount, datatype, comm, size)
returns in size an upper bound on the increment in position
that is effected by a call to MPI_PACK(inbuf, incount, datatype,
outbuf, outcount, position, comm).
Rationale.
The call returns an upper bound, rather than an exact bound, since the
exact amount of space needed to pack the message may depend on the
context (e.g., first message packed in a packing unit may take more
space).
( End of rationale.)
Example
An example using MPI_PACK.
int position, i, j, a[2]; char buff[1000]; .... MPI_Comm_rank(MPI_COMM_WORLD, &myrank); if (myrank == 0) { / * SENDER CODE */ position = 0; MPI_Pack(&i, 1, MPI_INT, buff, 1000, &position, MPI_COMM_WORLD); MPI_Pack(&j, 1, MPI_INT, buff, 1000, &position, MPI_COMM_WORLD); MPI_Send( buff, position, MPI_PACKED, 1, 0, MPI_COMM_WORLD); } else /* RECEIVER CODE */ MPI_Recv( a, 2, MPI_INT, 0, 0, MPI_COMM_WORLD) }
Example
An elaborate example.
int position, i; float a[1000]; char buff[1000] .... MPI_Comm_rank(MPI_Comm_world, &myrank); if (myrank == 0) { / * SENDER CODE */ int len[2]; MPI_Aint disp[2]; MPI_Datatype type[2], newtype; /* build datatype for i followed by a[0]...a[i-1] */ len[0] = 1; len[1] = i; MPI_Address( &i, disp); MPI_Address( a, disp+1); type[0] = MPI_INT; type[1] = MPI_FLOAT; MPI_Type_struct( 2, len, disp, type, &newtype); MPI_Type_commit( &newtype); /* Pack i followed by a[0]...a[i-1]*/ position = 0; MPI_Pack( MPI_BOTTOM, 1, newtype, buff, 1000, &position, MPI_COMM_WORLD); /* Send */ MPI_Send( buff, position, MPI_PACKED, 1, 0, MPI_COMM_WORLD) /* ***** One can replace the last three lines with MPI_Send( MPI_BOTTOM, 1, newtype, 1, 0, MPI_COMM_WORLD); ***** */ } else if (myrank == 1) { /* RECEIVER CODE */ MPI_Status status; /* Receive */ MPI_Recv( buff, 1000, MPI_PACKED, 0, 0, &status); /* Unpack i */ position = 0; MPI_Unpack(buff, 1000, &position, &i, 1, MPI_INT, MPI_COMM_WORLD); /* Unpack a[0]...a[i-1] */ MPI_Unpack(buff, 1000, &position, a, i, MPI_FLOAT, MPI_COMM_WORLD); }
Example
Each process sends a count, followed by count characters to the root;
the root
concatenates
all characters into one string.
int count, gsize, counts[64], totalcount, k1, k2, k, displs[64], position, concat_pos; char chr[100], *lbuf, *rbuf, *cbuf; ... MPI_Comm_size(comm, &gsize); MPI_Comm_rank(comm, &myrank); /* allocate local pack buffer */ MPI_Pack_size(1, MPI_INT, comm, &k1); MPI_Pack_size(count, MPI_CHAR, comm, &k2); k = k1+k2; lbuf = (char *)malloc(k); /* pack count, followed by count characters */ position = 0; MPI_Pack(&count, 1, MPI_INT, lbuf, k, &position, comm); MPI_Pack(chr, count, MPI_CHAR, lbuf, k, &position, comm); if (myrank != root) { /* gather at root sizes of all packed messages */ MPI_Gather( &position, 1, MPI_INT, NULL, NULL, NULL, root, comm); /* gather at root packed messages */ MPI_Gatherv( &buf, position, MPI_PACKED, NULL, NULL, NULL, NULL, root, comm); } else { /* root code */ /* gather sizes of all packed messages */ MPI_Gather( &position, 1, MPI_INT, counts, 1, MPI_INT, root, comm); /* gather all packed messages */ displs[0] = 0; for (i=1; i < gsize; i++) displs[i] = displs[i-1] + counts[i-1]; totalcount = dipls[gsize-1] + counts[gsize-1]; rbuf = (char *)malloc(totalcount); cbuf = (char *)malloc(totalcount); MPI_Gatherv( lbuf, position, MPI_PACKED, rbuf, counts, displs, MPI_PACKED, root, comm); /* unpack all messages and concatenate strings */ concat_pos = 0; for (i=0; i < gsize; i++) { position = 0; MPI_Unpack( rbuf+displs[i], totalcount-displs[i], &position, &count, 1, MPI_INT, comm); MPI_Unpack( rbuf+displs[i], totalcount-displs[i], &position, cbuf+concat_pos, count, MPI_CHAR, comm); concat_pos += count; } cbuf[concat_pos] = `\0'; }

Test looping by:
Play to end with 'loop' set to true.
When 'seeked' event fires, verify that time has jumped back and movie is playing.
Set 'loop' to false and play again.
Verify that 'ended' event fires.


Carefully validate filename and path input. Apply whitelist techniques when validating input.
Filenames and paths interact directly with the underlying filesystem. Allowing malicious users to manipulate file system operations directly or indirectly through their input can expose important sensitive system files. Canonicalization vulnerabilities can result in an attacker gaining access to unexpected resources.
The following code allows the user to read the contents of a report file, located in /myapp/temp/. Unfortunately, the code is missing filename validation; therefore, the application is exposed to a directory traversal attack:
import java.io.*;
import java.util.*;
import java.lang.*;

public final class ReportDownloader extends HttpServlet
{
public void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException
{
response.setContentType("application/vnd.ms-excel");
String baseDir = "/myapp/temp/";
PrintWriter out = response.getWriter();
String filename = request.getParameter("file");
BufferedReader fin;
String data = "";
try
{
File reportFile = new File(baseDir + filename);
// The application fails to validate the user-supplied filename
fin = new BufferedReader(new FileReader(reportFile));
StringBuilder sb = new StringBuilder();
while (data != null)
{
data = fin.readLine();
if (validateData(data))
{
sb.append(data);
}
else

// mechanisms. Consult the Exception Handling and

out.println("We cannot handle your request at the moment."

return;
}

out.println(sb.toString());
}
catch (Exception e)
{
// Add the appropriate logging and exception handling mechanisms

out.println("We cannot handle your request at the moment."

}
out.flush();
out.close();
}
boolean validateData(String input)

IDE integration
Meson has exporters for Visual Studio and XCode, but writing a custom backend for every IDE out there is not a scalable approach. To solve this problem, Meson provides an API that makes it easy for any IDE or build tool to integrate Meson builds and provide an experience comparable to a solution native to the IDE.
The basic tool for this is a script called mesonintrospect.py
. Some distro packages might not expose this script in the regular path, and in this case you need to execute it from the install directory.
The first thing to do when setting up a Meson project in an IDE is to select the source and build directories. For this example we assume that the source resides in an Eclipse-like directory called workspace/project
and the build tree is nested inside it as workspace/project/build
. First we initialise Meson by running the following command in the source directory.
meson build
For the remainder of the document we assume that all commands are executed inside the build directory unless otherwise specified.
The first thing you probably want is to get a list of top level targets. For that we use the introspection tool. It comes with extensive command line help so we recommend using that in case problems appear.
mesonintrospect.py --targets
The JSON formats will not be specified in this document. The easiest way of learning them is to look at sample output from the tool.
Once you have a list of targets, you probably need the list of source files that comprise the target. To get this list for a target, say exampletarget
, issue the following command.
mesonintrospect.py --target-files exampletarget
In order to make code completion work, you need the compiler flags for each compilation step. Meson does not provide this itself, but the Ninja tool Meson uses to build does provide it. To find out the compile steps necessary to build target foo, issue the following command.
ninja -t commands foo
Note that if the target has dependencies (such as generated sources), then the commands for those show up in this list as well, so you need to do some filtering. Alternatively you can grab every command invocation in the clang tools db format that is written to a file called compile_commands.json
in the build directory.
The next thing to display is the list of options that can be set. These include build type and so on. Here's how to extract them.
mesonintrospect.py --buildoptions
To set the options, use the mesonconf.py
binary.
Compilation and unit tests are done as usual by running the ninja
and ninja test
commands. A JSON formatted result log can be found in workspace/project/build/meson-logs/testlog.json
.
When these tests fail, the user probably wants to run the failing test in a debugger. To make this as integrated as possible, extract the test test setups with this command.
mesonintrospect.py --tests
This provides you with all the information needed to run the test: what command to execute, command line arguments and environment variable settings.
The results of the search are

Displays
All drawing operations end up being visible on a display which is the same as a window in windowed environments. Thus, before anything is displayed, a display needs to be created.
Before creating a display with al_create_display, flags and options can be set with al_set_new_display_flags and al_set_new_display_option. For example, you can enable the use of shaders or choose between the OpenGL and Direct3D backends (on platforms that support both) with al_set_new_display_flags. Display options are rather optional settings that do not affect Allegro itself, e.g. they allow you to specify whether you want a depth buffer or enable multisampling.
The actual properties of a display that has been successfully created can be queried via al_get_display_option, al_get_display_flags, al_get_display_width etc. Note that you can query some additional read-only properties such as the maximum allowed bitmap (i.e. texture) size via al_get_display_option.
Each display has a backbuffer associated to it which is the default target for any drawing operations. In order to make visible what has been drawn previously, you have to to call al_flip_display. Note that it is generally advisable to redraw the whole screen (or clear it in advance) to avoid artefacts of uninitialised memory becoming visible with some drivers.
You don't have to use Allegro's drawing routines, however: since creating a display implies the creation of an OpenGL context or Direct3D device respectively, you can use these APIs directly if you prefer to do so. Allegro provides integration for both (see the OpenGL / Direct3D sections), so you can retrieve the underlying textures of ALLEGRO_BITMAPs, for example.
In order to write a well-behaved application, it is necessary to remember that displays will also inform you about important events via their event sources.

MVP is generally used most often in enterprise-level applications where it’s necessary to reuse as much presentation logic as possible. Applications with very complex views and a great deal of user interaction may find that MVC doesn’t quite fit the bill here as solving this problem may mean heavily relying on multiple controllers. In MVP, all of this complex logic can be encapsulated in a presenter, which can simplify maintenance greatly.
As MVP views are defined through an interface and the interface is technically the only point of contact between the system and the view (other than a presenter), this pattern also allows developers to write presentation logic without needing to wait for designers to produce layouts and graphics for the application.
Depending on the implementation, MVP may be more easy to automatically unit test than MVC. The reason often cited for this is that the presenter can be used as a complete mock of the user-interface and so it can be unit tested independent of other components. In my experience this really depends on the languages you are implementing MVP in (there’s quite a difference between opting for MVP for a JavaScript project over one for say, ASP.net).
At the end of the day, the underlying concerns you may have with MVC will likely hold true for MVP given that the differences between them are mainly semantic. As long as you are cleanly separating concerns into models, views and controllers (or presenters) you should be achieving most of the same benefits regardless of the pattern you opt for.

C. Bala Manikandan, S.Balamurugan, P.Balamurugan, C.Thanga Priya}
Keywords: Mild steel, Banana peel extract, Corrosion inhibition, Corrosion rate, Weight loss measurements, Electrochemical techniques
Abstract:
Corrosion is the deterioration of metal by chemical attack or reaction with its environment. It is a
continuous problem, diï¬ƒcult to eliminate completely. The cost of metallic corrosion to the total
economy is in billions of rupees per year. The inhibiting action of the banana peel extract as a
corrosion inhibitor in controlling corrosion of mild steel in 0.1M HCl solution was studied. Corrosion
inhibition was identified by employing weight loss measurements and electrochemical techniques. Five
samples of mild steel specimen were taken and they are subjected to varying concentration of banana peel
extract solution for analyzing the inhibitory properties. The protective film has been analyzed using
FTIR spectroscopic techniques. The results indicated that the corrosion rate is decreasing as the
concentration of banana peel increases and simultaneously it enhances the inhibition efficiency of the
mild steel.


64. at-Taghabun: The Cheating
1
All that is in the heavens and all that is in the earth glorifieth Allah; unto Him belongeth Sovereignty and unto Him belongeth praise, and He is Able to do all things.
2
He it is Who created you, but one of you is a disbeliever and one of you is a believer, and Allah is Seer of what ye do.
3
He created the heavens and the earth with truth, and He shaped you and made good your shapes, and unto Him is the journeying.
4
He knoweth all that is in the heavens and the earth, and He knoweth what ye conceal and what ye publish. And Allah is Aware of what is in the breasts (of men).
5
Hath not the story reached you of those who disbelieved of old and so did taste the ill-effects of their conduct, and theirs will be a painful doom.
6
That was because their messengers (from Allah) kept coming unto them with clear proofs (of Allah's Sovereignty), but they said: Shall mere mortals guide us ? So they disbelieved and turned away, and Allah was independent (of them). Allah is Absolute, Owner of Praise.
7
Those who disbelieve assert that they will not be raised again. Say (unto them, O Muhammad): Yea, verily, by my Lord! ye will be raised again and then ye will be informed of what ye did; and that is easy for Allah.
8
So believe in Allah and His messenger and the light which We have revealed. And Allah is Informed of what ye do.
9
The day when He shall gather you unto the Day of Assembling, that will be a day of mutual disillusion. And whoso believeth in Allah and doeth right, He will remit from him his evil deeds and will bring him unto Gardens underneath which rivers flow, therein to abide for ever. That is the supreme triumph.
10
But those who disbelieve and deny Our revelations, such are owners of the Fire; they will abide therein - a hapless journey's end!
11
No calamity befalleth save by Allah's leave. And whosoever believeth in Allah, He guideth his heart. And Allah is Knower of all things.
12
Obey Allah and obey His messenger; but if ye turn away, then the duty of Our messenger is only to convey (the message) plainly.
13
Allah! There is no God save Him. In Allah, therefore, let believers put their trust.
14
O ye who believe! Lo! among your wives and your children there are enemies for you, therefor beware of them. And if ye efface and overlook and forgive, then lo! Allah is Forgiving, Merciful.
15
Your wealth and your children are only a temptation, whereas Allah! with Him is an immense reward.
16
So keep your duty to Allah as best ye can, and listen, and obey, and spend; that is better for your souls. And whoso is saved from his own greed, such are the successful.
17
If ye lend unto Allah a goodly loan, He will double it for you and will forgive you, for Allah is Responsive, Clement,
18
Knower of the Invisible and the Visible, the Mighty, the Wise.
-- Sura 64 --


PART I: Volge
In the gentle swirls of the river Epsilon, Volge floats in deep reverie.
Suddenly, he is rudely woken up by a dark figure towering above him -
"Get out," it shrieked, "you are not dead yet!"
Volge finds his way back ashore, and trudges through a quiet jungle littered with lightbulbs.
He collects an armful of them as if they were fruits.
Volge selects one and eats it.
"I suppose I shall go for another swim now," he said to nobody in particular.
PART II: Ande
Ande is quite fond of Shadows:
He likes them so much that he drinks one for breakfast every morning and never grows tired of it.
One day, the Shapes in Ande's favourite Shadow Lamp escaped. Out the window they went!
Here we see Ande trying to catch new ones. He is exhausted.
PART III: Betthe
Betthe collects Shiny Things because they make her happy.
There is a quiet jungle in her backyard which she decorates to her liking.
Occasionally she finds that her Shiny Things have been shattered and painted gold.
"Why, if only they weren't broken. I do really like this new colour."


Infinispan Operator 1.0.1 “Chupacabra Trainer”
Dear Infinispan community,
we know you are happy with the new shining 10.0.0 Infinispan release, but if you are among those who are missing a new operator version for safely running your Infinispan Chupachabra in the clound, this post is for you!
Versioning and channels
This is our first blog post about 1.0.x operator series (yeah, sorry 1.0.0 we forgot about you) and as you can notice there’s no Alpha, Beta or CR label at the end of the release tag. This is because OperatorHub and Openshift Catalog only allow numerical version like Maj.Min.Mic and instead of labels we now use the channel to indicate the stability of a release. We have 2 live channels at the moment for the Infinispan operator: stable
and dev-preview
. Current stable
is 0.3.2 which is for the 9.x Infinispan cluster and current dev-preview
is 1.0.1 which works with 10.x clusters.
New features
-
New Infinispan image configuration: we cleaned up the image configuration process: instead of rely on a large set of env variables, now the operator configures the Infinispan image via a single .yaml file.
-
Container configurability: CR .yaml file lets you configure memory and CPU (and also extras Java opts) assigned to the container;
-
Encryption: TLS can be setup providing TLS certificates or using platform service as the Openshift seriving certs service (TLS will be on by default in the next release);
-
We now have some good docs: https://infinispan.org/infinispan-operator/master/operator.html;
-
Project README has been also improved: https://github.com/infinispan/infinispan-operator/blob/1.0.1/README.md;
Get it
The Infinispan Operator 1.0.1 works on Kind/Kubernetes 1.16 (CI) and Openshift 3.11, 4.x (developed on). You can install it:
-
manually, follow the README;
-
with OLM on Kubernetes, https://operatorhub.io/operator/infinispan/dev-preview/infinispan-operator.v1.0.0
-
with OLM from the Openshift Operator Catalog
And remember: it’s a dev-preview release, you can have a lot of fun with it!
Contribute
As usual source code is open at: https://github.com/infinispan/infinispan-operator. You can see what’s going on, comment the code or the new pull requests, ask for new features and also develop them!
Thanks for following us, Infinispan

Propagation is the prediction of the evolution of an initial state. This initial state is represented in OREKIT by a {@link org.orekit.propagation.SpacecraftState}, which is a simple container for all needed information : mass, {@link org.orekit.utils.PVCoordinates kinematics}, {@link org.orekit.attitudes.Attitude attitude}, {@link org.orekit.time.AbsoluteDate date}, {@link org.orekit.frames.Frame frame}. Several ways to calculate this prediction and store its results are proposed to the user.
The mathematical problem to integrate is a seven dimension time derivative equations system. The six first equations are given by the Gauss equations (expressed in {@link org.orekit.orbits.EquinoctialOrbit}) and the seventh is simply the flow rate and mass equation. This first order system is computed by the {@link org.orekit.propagation.numerical.TimeDerivativesEquations} class. It will be instanced by the propagator and then be modified at each step (a fixed t value) by all the needed {@link org.orekit.forces.ForceModel force models} which will add their contribution, the perturbing acceleration.
The {@link org.apache.commons.math.ode.FirstOrderIntegrator integrators} provided by commons-math need the state vector at t0, the state vector first time derivate at t0, and then calculates the next step state vector, and ask for the next first time derivative, etc. until it reaches the final asked date.

This is a project for IS601-Web Systems Development subject taken by Professor Keith Williams.
My name is Harshad Jadhav and I am currently pursuing my Master's degree in computer science. This is my first semester and I took this course because I am interested in gaining more in depth knowledge in Web Development.
I have used the following tools and software's for our project:


Created by:
Stephan Meissl, Thomas Bonfort, and Fabian Schindler

I work at the Queensland Functional Programming Lab.
It's my job to help FP succeed and give local business a competitive advantage with FP
I'm a webapp guy on a mission to make full stack haskell dev awesome! :)
I love building software that is tangible, pretty and ultimately improves people's lives
But it sure is a pain even with the best of breed tools at the moment
Reflex is an overloaded term that means many things
The base FRP library
Gives us a fundamental structure for programming over time varying state.
Web agnostic!
A DOM Building framework built on Reflex & GHCJs
A framework on top of reflex-dom that deploys to browser, iOS and Android
A bit like react native
A full stack framework on top of reflex platform
Batteries included: Server side rendering, routing, deployments...
If you are learning reflex, it is best to start here
UIs are Hard
Ofter tangled messes of time varying state
Out best of breed tools centralise state
But this feels antimodular and makes me want something better
FRP gives us a fundamental way model time varying state into the essense of our programs
And this fundamental jump seems critical for us as our programs become more and more distributed
FRP is hard to learn
Like the jump from Imperative -> FP
It's hard to see how it relates to your apps when you are learning fundamentals
Skip you ahead a bit so you can see how a non-toy reflex app looks
Ground reflex in a familar setting and language
To motivate you to play further and learn the fundamentals
The reducer of the reflex world
exFoldDyn = do
buttonClickE :: Event t () <- button "Click me"
let reducer _ old = old + 1
clickCountDyn :: Dynamic t Int <- foldDyn reducer 0 addE
text " Clicked: "
display clickCountDyn
text " times!"
> import Data.Monoid.Endo
> let idEndo = mempty :: Endo Int
> let incEndo = Endo $ (+ (1::Int))

let addE = Endo (+1) <$ addClickE
let resetE = Endo (const 0) <$ resetClickE
let updatesE = addE <> resetE :: Event t (Endo Int)
clickCountDyn <- foldDyn appEndo 0 updatesE
Redux apps are tidy because the dispatcher and subscriptions
Not having to bubble events manually and pass state down makes refactoring and reuse easier
Reflex analog to dispatcher
addButton :: (DomBuilder t m, EventWriter t (Endo Int) m) => m ()
addButton = do

The Gross Operating Income (GOI) - also called Effective Gross Income (EGI) - is the amount of income produced by a piece of property, plus miscellaneous income, less vacancy costs and collection losses. Gross Operating Income is a metric commonly used to evaluate the value of a piece of investment property.
GOI = GSI x VCL
Example:
For example:
GSI = 500,000
VCL = 20%
GOI = 500000 - (.2*500000)
GOI = 500000 - 100000)
GOI = 400000)

LOAD CDN FILE LISTINGS
When The Handpicked jQuery Plugins Repository first launched in 2011, it was a basic site with a handful of cool plugins, and not looking great in terms of design.
The site constantly went down due to new demand for curated plugins, and the official jQuery plugins registry was famously down for the best part of a year. People needed their jQuery fix, and I was giving it to them.
The site gets increasingly lean and mean over time. Outdated plugins get removed, and new ones take their place. The colors change, the CDN gets better, and more new fans download the repo each day to experiment with the plugins.
The awesome people at MaxCDN are sponsoring us, and this allows the site to load much faster. Others can hotlink to scripts, and browsing the site feels much faster. All the plugins are served from Github Pages, so the site is easier to maintain.
I have done lots of behind-the-scenes plumbing to get these plugins loading as fast as possible. There is even a sister site that enables you to easily copy and paste any version of jQuery you want to use whilst coding.
Version 3 is the full expression of this repo as it stands now. I could not have hoped for a more gorgeous selection of plugins coded by some very talented people. Bear in mind, all this is open source, and on Github.
Thanks to everybody who has shared the URL on Twitter or linked to the Repo elsewhere. It's the fans that make this Repo get smarter, better, and stronger each year. If you write jQuery plugins and feel like your plugin deserves a place here, you can use the feedback form, or simply contact me.
- David Higgins (Curator, Designer, and coder of The Repo).
The Handpicked jQuery Plugins Repository is a carefully selected roundup of some of the best jQuery Plugins ever released. Here we offer you the ability to browse through the plugins, or download a plugin that you fancy. Whether you're building a huge Web-Application, or a simple site, we've got you covered. We also offer you the ability to hot-link directly to these plugin scripts through our CDN service, so your site loads much faster.
Below is a list of CDN URLs you should use if you're going to implement a plugin on your site. We are on a dedicated MaxCDN setup so all JS is Gzipped and served from 16 "edge locations" from around the world for peace of mind.

Advanced tools for the GitHub-powered maps.
GitHub recently introduced
support for
rendering maps from .geojson
files.
While I like that feature a lot, I feel that it's a bit limited
(eg. missing editing support), so I wrote an application
specifically tought for dealing with maps on GitHub.

The plugin is able to display objects in the sky, such as stars, constellations, planets, the Earth's moon, and galaxies. When the application switches to Sky mode, the viewport transitions to show the sky at a point above the camera's current position, as measured from the center of the Earth (the zenith). The celestial data is mapped onto the inside of a virtual sphere that surrounds the Earth.
Use the following set
method to display Sky mode:
ge.getOptions().setMapType(ge.MAP_TYPE_SKY);
Use the following set
method to display Earth mode:
ge.getOptions().setMapType(ge.MAP_TYPE_EARTH);
Source: http://earth-api-samples.googlecode.com/svn/trunk/examples/sky.html
ge.getOptions().setMapType(ge.MAP_TYPE_SKY); var lookAt = ge.createLookAt(''); lookAt.set(41.28509187215, -169.2448684551622, 0, ge.ALTITUDE_RELATIVE_TO_GROUND, 262.87, 0, 162401); ge.getView().setAbstractView(lookAt);
Celestial coordinates are described in terms of right ascension (RA) and declination. Right ascension, which corresponds to longitude, represents a distance from the point in the sky where the sun crosses the celestial equator at the vernal equinox. Right ascension is measured from 0 to 24 hours, with one hour of RA equal to the amount the sky rotates above a given point on the Earth's surface in one hour of time. Zero hours of RA is at the point of the vernal equinox, with RA increasing eastward from that point.
Declination coordinates correspond directly to latitude values, ranging from −90° south of the celestial equator to +90° north of the celestial equator.
When you use the LookAt object with sky data, you need to perform the following calculations to determine the range. The basic formula is as follows:
r = R*(k*sin(β/2) - cos(β/2) + 1)
where:
<LookAt>
element
Note: The Google Calculator is a handy tool for making such calculations.
Here are some sample ranges:
The Google Earth Plugin isn't just the Earth and the sky - you can also view detailed
imagery of Mars, including 3D terrain. To do so, specify the Mars imagery database
when calling the google.earth.createInstance()
function:
google.earth.createInstance('map3d', initCB, failureCB, { database: 'http://khmdb.google.com/?db=mars' });
Unlike Earth and Sky modes, which use MAP_TYPE_x
arguments, Mars
can only be loaded upon plugin initialization. To switch from Earth to Mars,
you'll need to clear the existing Earth instance before loading a fresh Mars instance:
function showMars() { document.getElementById('map3d').innerHTML = ''; google.earth.createInstance('map3d', initCB, failureCB, { database: 'http://khmdb.google.com/?db=mars' }); }
LookAt and Camera views on Mars work the same way as on Earth. Some interesting locations to get you started are below (view them in the plugin).
lookAt.set(18.4, -134, 0, ge.ALTITUDE_RELATIVE_TO_GROUND, 0, 0, 650000);
lookAt.set(40.717, -9.424, 0, ge.ALTITUDE_RELATIVE_TO_GROUND, -44.158, 0, 10150);
lookAt.set(-6.276, -69.939, 0, ge.ALTITUDE_RELATIVE_TO_GROUND, 3.095, 35, 52800);
As with Mars, the moon view requires that its imagery database be specified upon plugin initialization. To do so:
google.earth.createInstance('map3d', initCB, failureCB, { database: 'http://khmdb.google.com/?db=moon' });
LookAt and Camera views on the moon work the same way as on Earth. Some interesting locations to get you started are below (view them in the plugin).
lookAt.set(0.681400, 23.460550, 0, ge.ALTITUDE_RELATIVE_TO_GROUND, -1.946649, 0, 130);
lookAt.set(-16.800000, 173.400000, 0, ge.ALTITUDE_RELATIVE_TO_GROUND, -4.378803, 0, 135000);
lookAt.set(25.238916, -21.138078, 0, ge.ALTITUDE_RELATIVE_TO_GROUND, -1.811669, 0, 78000);

This page is for tracking Gab's status during downtimes.
I set up a Gab Haven group on MeWe, as a temporary gathering place, during outages.
Send news to<EMAIL_ADDRESS>Gab.com starting late on 28 October, 2018:
Gab.com is under attack. We have been systematically no-platformed by App Stores, multiple hosting providers, and several payment processors. We have been smeared by the mainstream media for defending free expression and individual liberty for all people and for working with law enforcement to ensure that justice is served for the horrible atrocity committed in Pittsburgh. Gab will continue to fight for the fundamental human right to speak freely.
As we transition to a new hosting provider Gab will be inaccessible for a period of time. We are working around the clock to get Gab.com back online. Thank you and remember to speak freely.
From Andrew Torba, 2018-10-28T16:56:59+00:00:
New hosting provider secured. Working around the clock to see to it that Gab.com stays online. You can't stop the power of The People in their fight for freedom and liberty against tyranny.
FREE SPEECH WILL ALWAYS WIN.
From Andrew Torba, 2018-10-28T01:51:51+00:00:
Breaking: @joyent, Gab's new hosting provider, has just pulled our hosting service. They have given us until 9am on Monday to find a solution. Gab will likely be down for weeks because of this. Working on solutions. We will never give up on defending free speech for all people.

Houthis Demand Sudan Withdraw From Arab Coalition in Yemen
BEIRUT (Sputnik) - The Houthi movement has addressed Sudanese people to demand that their country withdraw from the Arab coalition in Yemen, urging them to look at heavy casualties their military is allegedly suffering.
"You overlook the number of your soldiers who have been killed while fulfilling tasks of the enemy coalition. There are hostages, as well as those killed and wounded. Changes in Sudan seem incomplete against the backdrop of Sudan's continued involvement in the coalition’s actions," Houthi military spokesman Yahya Saria said in a televised address.
According to the spokesman, 4,253 Sudanese soldiers have been killed since the coalition became involved in the Yemen conflict. Coupled with those injured, this number totals 8,000.
Since the very beginning, Saria says, the Sudanese military has been sent to the front line.
The Saudi-led coalition has been providing military assistance to the internationally recognised Yemeni government in its fight against Houthi rebels since March 2015. Sudan, the United Arab Emirates, Bahrain, Kuwait, Egypt and Jordan are among members of the coalition.
The conflict has been described by the United Nations as the world’s worst humanitarian crisis, with an estimated 24 million people - nearly 80 per cent of the Yemeni population - currently in need of aid and protection.


Veda Krishnamurthy’s 57 helps India Women claim 5-0 T20I series sweep over West Indies
Rodrigues scored 50 runs from 56 balls, which was studded with three boundaries, while Krishnamurthy's unbeaten career-best 57 came off 48 deliveries.
by PTIThe Indian women’s cricket team completed a 5-0 series whitewash over the West Indies after half-centuries from Veda Krishnamurthy and Jemimah Rodrigues, complemented by the bowlers’ clinical show, steered the side to a 61-run triumph in the fifth and final T20 International here.
Rodrigues (50) and Krishnamurthy (57 not out) shared 117 runs for the third wicket as India Women scored 134 for 3 after electing to bat.
The decision seemed to have backfired when India were reduced to 17 for 2 in the fourth over with Shafali Verma (9) and captain Smriti Mandhana (7) getting out cheaply.
But the Rodrigues-Krishnamurthy duo steadied the innings and took the side to a decent total.
Rodrigues scored 50 runs from 56 balls, which was studded with three boundaries, while Krishnamurthy’s unbeaten career-best 57 came off 48 deliveries, which included four hits to the fence.
In the West Indies run chase, the Indian Women bowlers produced a disciplined performance to restrict the hosts to 73 for 7 in their allotted 20 overs.
The West Indies were 13 for 2 in the fourth over and they never recovered from that. Half of their batters were out for 53 runs in the 14th over.
Opener Kyshona Knight was the top-scorer with 22 while Shemaine Campbelle remained not out on 19.
For India Women, off-spinner Anuja Patil grabbed two wickets for just three runs while Radha Yadav, Poonam Yadav, Pooja Vastrakar and Harleen Deol took a wicket each.
Brief Scores:
India Women: 134 for 3 in 20 overs (Jemimah Rodrigues 50, Veda Krishnamurthy 57 not out; Hayley Matthews 1/23)
West Indies Women: 73 for 7 in 20 overs (Kyshona Knight 22; Anuja Patil 2/3).


Fancy Restaurant, Chapter One: #Fruit Platter
With the title ‘Fancy Restaurant, Chapter One: #Fruit Platter’, this project satirizes and questions the contradictions between people in the network and in reality through a combination of humorous and poetic words and various sculptural objects. By questioning a series of social phenomenons such as taking photos before meals, it reveals the fact that people relies on the “parallel self” in the digital world to “correct” the real world of life. Using hashtags from social platforms
as the breakthrough element, it selects several top listed hashtags on instagram to involve in the narratives. The title ‘fruit platter’ metaphorizes a formalistic beauty that is deliberately created for visual effect.
